I’ve been thinking about this since I saw an article in BYO where two brewers showed how to use an in-line filter to dry hop their beer in the secondary. The concept was simple; hops go into the in-line filter and the filter, with a few barbs and hoses on the end, gets dropped into the secondary.
It took me a little bit of thinking before I came up with my idea, but once I did, it seemed to make sense. While in-line filters are actually kind of hard to find, I was able to locate one on the web for like $10. My plan was simple, set this thing up to that it fits into my racking process so that the beer runs through the in-line filter before it goes into the keg.
So, I want the hose that connects to the racking cane to run into the in-line filter and then into my keg. Simple enough. The parts were pretty basic:
2 nylon barbs, 1/2 with a 3/4in thread
1 swivel hose adapter 3/4 to 3/4in
Put together, it looks something like above. While the concept was sound, the swivel 3/4 to 3/4 adapter doesn’t seal so there is no suction. The swivel adapter is not necessary, so I’m going to give it another run with something a little more secure.
One quick note is that I boiled all of the parts before trying them and got some petroleum byproducts in the water they were boiled in.
More to come on this, I will be updating, but thoughts and comments on this are welcome…
